BlackBerry Ltd. shares soared nearly 30 percent on a report that says Samsung is considering a possible takeover of the company.

The Reuters report, citing unnamed sources, said that executives met last week to discuss a potential deal. South Korea-based Samsung reportedly offered to buy BlackBerry for as much as $7.5 billion.

Samsung declined to comment. Messages left with BlackBerry were not immediately returned.

Shares of BlackBerry jumped $2.89 Wednesday to close at $12.60 and continued to gain in after-hours trading.
